Spouse Visa

I am a British citizen by naturalization and want to bring my wife and 2 years old daughter to UK from a Non-EU country. My daughter was born after I became British citizen. I am earning £23000 per annum which meets the financial requirement of a spouse visa with one child.
My query is related to help with housing cost and can someone kindly answer it.
At present, I am renting a small room in a shared flat in London but when they come over here, I will have to find one bed flat or least studio flat which is unaffordable with my salary unless I am eligible to get help with housing cost.
1. Do I have to rent one bed/studio flat when apply for visa?
2. Once my family is here, can I claim for housing benefit or working tax or child tax credit or any kind of benefit to get help with my rent?
If I don’t get help with rent, then after paying rent for a studio or one bed flat I won’t have enough money to feed myself and my family. I need to make the decision based on this information.

1. You'll need at least 1 bedroom flat with a sitting room which can be counted towards a bedroom. Child will count as needing 0.5 of a room.

2. With your salary I doubt you will not get any housing benefit at all. You will most likely not get any housing benefit at all.

Saying The processed visa application for GWF reference number - GWF******* was received at the UK Visa Application Centre on 12/20/2018

I’m really scared it may be refused as he still has not received any message saying his passports due to be collected... but then thinking the weekend came in between... and blue dart tracking website says due to be delivered 24/21/18
